"""
TOPS software installer. This is written using the EasyGui.py python module
which is, for simplicity, included in this file 

EasyGui provides an easy-to-use interface for simple GUI interaction
with a user.  It does not require the programmer to know anything about
tkinter, frames, widgets, callbacks or lambda.  All GUI interactions are
invoked by simple function calls that return results.

Documentation is in an accompanying file, easygui.txt.

WARNING about using EasyGui with IDLE
======================================

You may encounter problems using IDLE to run programs that use EasyGui. Try it
and find out.  EasyGui is a collection of Tkinter routines that run their own
event loops.  IDLE is also a Tkinter application, with its own event loop.  The
two may conflict, with the unpredictable results. If you find that you have
problems, try running your program outside of IDLE.

Note that EasyGui requires Tk release 8.0 or greater.
